For medicinal and recreational users of marijuana, April 20 is a day of celebration and a chance to raise awareness about the semi-legal drug. Bleacher Report used the day to feature several notable former NBA and NFL athletes sharing their stories of cannabis use before, during and after their careers. Three prominent former Denver athletes appear in the special.

Former Nuggets star forward Kenyon Martin, former Broncos All-Pro offensive tackle Ryan Clady and former Titans and Bengals tight end and Mullen (Denver) High School standout Bo Scaife were members of the panels that joined B/R host Master Tesfatsion in a smoking session and roundtable discussion about their use.

Clady, who was the Broncos’ top pick in the 2008 draft (No. 12 overall) says his consumption of cannabis began in college. Clady was a consensus All-American for the Boise State Broncos before going on to earn two first-team All-Pro designations with the professional Denver Broncos.

He explained smoking for the first time in college, and although he says the first time he smoked he didn’t feel it, he recalls smoking out of an apple later in college and being “so high I’ve never laughed that much before in my life.”

While some players on the panel spoke about the psychoactive reaction of the drug, putting them “in the zone” for games, Clady was quoted in the special – a slideshow of 50 panels – suggesting the benefits of the drug in helping him physically recover.

“Every weekend is like a car wreck, and you start feeling better about Friday or Saturday,” Clady said.

Martin echoed those sentiments, crediting marijuana for helping him recover from numerous injuries throughout his career.

“I played 15 years, man, like, and made it through a lot of major injuries and still was able to play at a high level,” Martin said. “You know, and that’s through most of my career, you know what I’m saying, was self-medicating. I’m the only athlete – basketball player – to come back from two microfracture surgeries on each knee and play basketball. Like, that’s medicine. I’ve had major reconstructive surgery on my left ankle. I’ve had my patella repaired. Like, I walk around, man, in no pain.”

Martin even admitted to smoking before a game in Indiana, to self-medicate for a “hamstring, hip or something,” and then “went out there and had a great game.” He did not indicate whether that game was with the Nuggets or another of his four NBA teams.

Martin played in Denver from 2004-2011, averaging 30.6 minutes per game over 371 games for the Nuggets. As he indicated in the special, Martin underwent microfracture surgery on each knee – his left in 2005 and his right in 2006. He returned to play 71 games in the 2007-08 season for Denver, helping the Nuggets to 50 wins.

Marijuana remains a banned substance in both the NBA and NFL, although the panels in the Bleacher Report special suggest that the ban is more posturing than practical. Martin suggested that 85 percent of NBA players were using, while Martellus Bennett suggested that player usage in the NFL was “about 89 percent.”

Testing in the NFL, as Scaife explained, was timed so that players knew when to expect tests. They happened “usually in the springtime before OTAs or right after OTAs start,” Scaife said, also saying. “The NFL knows what’s going on.”

Players are well aware of the timeline, Scaife suggested: “Guys want to be tested early so they can get back on it.”

Clady, if given the opportunity to speak to Roger Goodell, would ask the NFL Commissioner this: “Why have that once-a-year test when it’s so beneficial to all the players who use it?”

Both the NFL and NBA have said publicly that they will continue to monitor medical studies about the potential health benefits to marijuana. However, as state-by-state laws differ on its legality. Medical use, by doctor’s recommendation only, is legal in 46 U.S. states. Recreational use is legal only in Alaska, California, Colorado, Maine, Massachusetts, Nevada, Oregon, Washington state, and Washington DC (with Vermont to follow later this year).
